It is 2 am here and I am missing all that food!! There is NOTHING that can rival Msian street food. Most of the faves u listed, I have to add, originated from Penang. So, for the real deal and at a much cheaper price, u'll have to try Penang! For the grilled sting ray, try using Tean's fish sambal paste as a marinade. Btw, hope u picked up some of Tean's Gourmet products; most authentic and priced reasonably. Exported to Aust, Canada and the US, so I think should be available in HK.
